Note that while this is "optimal" placements, it is not the best sequence in-game. For example, sequence 8, 9, 10, 11, and 12 are going backwards. I'm not sure how to rewrite my program to account for the top-down placements per round however. So there's still work to be done.

This was a relatively simple brute-force bot that exhaustively checked all possibilities for the best possible placement. So I'm pretty sure I've go the best placement here. Well, maybe it was more "Dynamic Programming". I worked backwards: I calculated all possible 17-placement endgames (there's only 1.081 million of them, aka 25-choose-17), and then back-calculated all possible moves back to move#1.

Then I calculate from move#1 forward, choosing the best endgame move now that all possible endgames have been searched. Chess-programming fans would know this as a "Tablebase" approach.


EDIT: Searching the ~60 million possible optimal games proved to be difficult, as my computer ran out of RAM at 2GB (ummm... I got a 32GB system here. WTF Windows?). I'm sure there was some compiler flag I messed up on.

But I did a few heuristics and came up with the following board:

This is a 17-placement across 5 rounds with as many placements on the "top" of the board that I could find with my program.

I've added a new placement based on a few more heuristics.

The newest placement is theoretically possible in 5 rounds, creates the maximum 113 score, and is biased to have as many placements as "high" up as possible (row1 favored most, row2 next favored, etc. etc.)
